PHYWE 11226-99 光速计 (50.0 MHz)

- Function and Applications:

With the Speed of Light Meter you can measure the velocity of light in air and in other transparent media and additionally you can determine the distance.

- Benefits:

• Measuring the speed of light, as well as distances, with only one device all thanks to state-of-the-art digital measuring technology

• The unit is convincing by a quick set-up and a need of minimum adjustment

• The speed of light can be measured with an accuracy in air of +/- 2%

• Measurements can be performed with or without an oscilloscope

• Due to the integrated display of all of the relevant measurement quantities (ƒ, Δφ, Δt, Δx) the unit is of special interest for student and teacher experiments

• Distance measurements can be performed with the same device
